MACHINE FOR mANUIAcTURING WIRE GARMENT HANGERS.

Application filed August 5, 1926. Serial No. 127,317.

This invention relates to wire working machines and more particularly to machines for manufacturing wire coat or garment hangers.

Wire coat hangers (coat and arment hangers) of the type here contemp ated are now largely used by garmentcleaners and pressers, and are a well known and staple article, It is-now customary for cleaners and pressers on such hangers and to supply the hangers without cost. The hangers, therefore, must be comparatively cheap and one object of this invention is to produce a machine or apparatus by means of which such hangers may be made in relatively large quantities and at a relatively low cost.

Another object of this invention is to produce a machine orapparatus for manufacturing such-hangers which is simple in construction, relatively chea to manufacture, which requires but relative y small floor space, and which is entirely automatic in its operation. A further object of this invention is to produce a ma'chine or apparatus into which the wire is fed from a reel, is straightened, out to length, has one end thereof bent to form a hook, hanger, has the ends twisted one about the other and is discharged from the machine. These, as well as other objects, which will be apparent to those skilled in this particular art, I attain by means of the machine or apparatus described in the specification and illustrated in the drawings accompanying and forming part of this application.

Instead of supplying the-"machine with wire that has been straightened and cut to length as is now done in some types of machines used for manufacturing arment hangers. the wire in this machine is ed from a reel and the machine itself straightens and cuts the wire to length. The reel is preferably provided with a vertical axis and is adapted to carry a coil of wire in such position as to be easily led to the feed rolls of the machine.

The entire formation of the hanger takes place in one plane and in the machine chosen for illustration, this plane is horizontal. It will be apparent, however, after the construction and operation of the machine is understood, thatthis could as well be a vertical plane.

a eneral way the machine consists of feed re s which pu l the wire from the reel and force or push it into position in the machine. After leaving the feed rolls, the wire isforced through straightening rolls, thence a cutter and through a guideway to the B813 Far end of the machine where it strikes against tlon of the feed rolls.

a tripping mechanism which, operating in conjunction with the cam for controlling the o ration of the feed rolls, times the separa- The feed rolls are continuously driven and while held in inoperative position by means of a spring, are periodically closed so that the wire feedis intermittent, but regultlu'ly ead against rotation during the timed to co-ordinate with the other mechanisms.

The wire in its passage through or into the machine moves past a stationary former plate and when the wire is brought to rest in the machine and is severed, it projects a greater distance on one side ary former plate than on the other. As soon as the wire comes to rest in the machine, the

hook is formed in the long end of the wire and the other end of the wire is severed. The ends of the wire are then bent around the former plate by means of swinging arms. The active faces of these arms are channeled and made to conform to the contour of the former plate which they overlap.

The swinging arms force the ends of the wire (one with the hook and one plain) beof the stationtween rigid 'aws in the twister head. The

another length of wire isforced into position in the machine.

The'machiae in detail.

The machine is provided with a horizontal bed or table 30 sul iported by suitable standards or legs-31. he. wire guides, the. stationar former plate, the forming arms, the hook ormer and the twister are all located above the bed 30 and operate in the plane of the wire in its passage into position in the machine. l

The cams for operating the different parts of the machine in timed relation one to the other are mounted one main shaft 32 of the machine and-this main shaft is journaled in suitable bearings in hangers such as 33, Figs. 2 and 34, (Figs. 11, 12, 15 and 19,) depending from the under side of the bed.

,The wire feeding mechanism.

The feed or pinch rolls 35 and 36 are res ectively mounted at the outer ends of shafts 37 and 38. Shaft 38 is journaled in fixed bearing blocks 39 and 40 which are secured to and supported u n a shelf 41 formed on standards'31. The shelf is located below the level of the bed 30. Bearing blocks 39 and 40 are located between two vertically extending and spaced side lates 42 and 43 which are secured to shelf 41.

haft 37 for the upper pinch roll 35 is journaled within a U-s aped frame member 44 which slidingly fits between side plates 42 and 43 and the frame .is mounted for pivotal movement on pivot studs 45 which are threadframe 44 adjacent roller is normally lifted are bearing blocks away from the top of bearin block 44 by means of a stiff coil spring 46 w ich is located in aligned recesses in the'bottom of bearing frame 44 and the top of bearing block 40.

The upward movement of U-shaped frame 44 about pivot of an adjustment screw 47 which is threaded through a bar 48 which in' turn is secured to side plates 42 and 43. ,The inner end of adjustment screw 47 is adapted to bear against a hardened abutment member 49 secured in place in the top of U-shaped frame 44 in-line with the adjustment screw.

The rolls 35 and 36 are grooved as shown in Figs. 2 and? so as to pinch or grip the wire forced thereby into position in the machine. V

Shaft '38 carries a worm wheel 50 which meshes with a worm wheel 51 keyed to main cam shaft 32. Shaft 38 carriesja gear 52 that meshes with a gear 53 carried by shaft 37. Shaft 38 is also provided with a drivg ing pulley 54 and a loose pulley 55.

Bolted to the tops of side plates 42 and 43 56-56 and journaled within these is an actuator member 57 The forward end of this member is drilled and tapped to receive an adjustnient'scrcw- 58 and the lower end of this screw bears against a hardened abutment member 59 which is let into a hole drilled for that purpose in the topof U-shaped frame 44." Actuator member' 57 which is provided with trunnions upon which the same is pivotally swung, has one of these trunnions 60 extended beyond its bearing block and keyed to this extension is an operating level 61.

A cam 62 provided with a. cam roller 63 is mounted on main shaft 32 in line with lever 61. The cam rotates in the direction of the arrow and raises lever 61 intermittently and thereby depresses pinch roll 35 through the agency of screw 58 which is carried by the actuator 57 to one trunnion of which lever 61 is secured.

Lever 64 mounted on a vertical pivot pin 65 secured to a supporting pad 66 has its inner end stepped as shown at 67. This stepped end is urged toward the'machine and into the path of lever 61 by means of a coil spring 69 which is positioned between the outer end of the lever and the end of the machine. From this construction, it will be seen that as lever .61 is raised by cam 62, stop 67 will move into the path of lever 61 and will .retain the lever in raised posit-ion when cam lever 63 is moved out of contact with the lever 61. A tripping mechanism. to be hereinafter described. is utilized for timing the release of lever 61 and therefore the separation of pinch rolls 35 and 36 and consequently the feed of the wire.

A thrust bearing studs 45 is limited by means- 7 0 is provided in order to take care of the end thrust of-worm 50v and a housing 71 for worm wheel 51 is provided and is adapted to be filled with lubri- .cant for the worm 50 and the worm wheel 51.

The we're straightening mechanism.

The wire. for supplying the machines is obtained in standard coils and the coils are supported upon a reel having a vertical axis. The wire as it emerges from the pinch rolls 35and 36 passes through a series of straightening rolls 72. ening rolls have vertical axes and part have horizontal axes. arranged thus in order that the wire as it emerges therefrom will be straight.

The wire upon emerging from the straightening rolls is forced throu h a drilled cutter block 73 which is preferahly hardened and provided-with a bell mouth 74. A cutter bar 75 secured to the upper end of a lever arm 7 6- is periodically moved across the cutter block ;7 3 to sever the wire into suitablelengths for forming the hangers. Lever 76 is pivotally mounted at 77 and has its lower end connect-' ed by means 'of an adjustable link 79 to a swinging lever arm 78 provided with a cam surface 78. A tension spring 80 secured to swingin g lever 78 yieldingly holds cutter bar 75 in inoperative position so as to clear the opening through cutter block 7 3. A cam roller 82 is mounted in the end of a supporting arm 81 keyed tated in the direction of the arrow. It is apparent that this mechanism will periodically move the cutter bar 75 across the path of the wire extending through cutter block 73 and thus sever the same.

The wire, upon emerging from the cutter block 73 enters a wlre guidlng device'which' guides it in a straight line to the. far end of the machine where it contacts with a trig-- ger.block 84.

The bed or table 30 is cut away at 83 to receive lever 76 and the cutter bar and supports attached thereto.

The we're gwidz'ng device.

Part of the series of straight The straightening rolls are to main shaft 32 and roand the top edge 93 are so shaped as to give the prop-er contour to the finished hanger.

The former plate 90 is supported a slight distance above the bed'plate by a spacer plate 94. The spacer plate at its back edge is straight from end to end and projects rearwardly beyond the back edge-0f the former plate a distance slightly in excess of the diamsecured to the eter of the wire. A back bar secured to the bed 30 and abuts against the back edge .of the spacer plate 94 thus forming a wire channel etween the back of the former plate and the back bar 95. This back bar extends the length of the former plate. A guide bar 96 that normally rests on the to of back bar 95 covers the wire channel provided between this bar and the back of the former plate and the guide bar is provided wardly extending L-shaped arms 97 the lower ends of which are hinged at 98 to bracket members s-ecured to the bed late.

A link 99 the length of which is adjustable by means of a screw 100, is connected at 101 to one of the L-shaped arms 97 and at 102 to the free end of a cam lever 103. Lever 103 carries a contact roller 104 and main shaft 32 carries a cam 105 for periodically raising the bar 96 to inoperative position. The bar is moved by gravity to operative position.

Bar 96 adjacent its opposite endsis provided with two pivotally mounted L-shapcd guiding members 106. Each of these members is pivotally connected between a pair of arms 107 which arms are spaced apart and, project forwardly from the bar 96. Each of these L-shaped bars is yieldingly urged into operative position by means of a coil spring 108 (Figs. 1 and 14). When bar 96 is in operative position, the lower legs 109 of L-shaped members 106 abut against back bar 95 and lie under bar 96 thus forming movable bottoms for portions of the wire guiding channel.

The hbol: foaming mechanism. 7

The hook forming mechanism (Figs. 15, 16, 17 and 18), comprises a stationary pin 110 guide bar 96' and extending vertically downward to the bed plate, a grooved roller lllspaced from the pin and mounted on a stud secured to the bed plate and a roller 112. Roller 112 mounted on a stud 113 secured to a swinging arm 114 carried on a block 115. Block 115 is rovided with an upwardly projecting edge 116 and the swinging arm is yieldingly 'held in normal position against this' lprojecting edge by means of a spring 117. he rear end of arm 114 is cut away as shown at 118 so as to allow a limited swingin movement to the arm at right angles to the line of travel of the wire into position inthe machine.

A guide plate 119 having a curved guide surface 120 is secured to the bed in the nth of travel of roller 112 while moving to ook forming position.

Block 115 is pinned to a reciprocating rod 121 and the rod is prevented from turning by means of a guide rod 122 which lies between ears 123 which extend downwardly from block 115. Rod 121 carries a block 124 which is pinned thereto and between thisblock and part 125 of the with two rear-- this bent en then locking the b jto the position shown by to block 124on the reciprocating rod 121. The lever carries a 1'0 ler 131 with which roller cam 127 is adapted to contact. The cam forces rod 121 against the stress of spring 126 and reciprocates the rod in one direction the spring moving the rod in the opposite direction.

Fig. 17 shows the wire W in position in the machine and before the hook former begins to operate. When rod 121 is moved by cam 127 into hook forming position (Fig. 18) the wire is bent against pin 110 and between it and grooved roller 111. The guiding surface 120 of guide plate 119 causes pivoted arm 114 to the position shown in Fig. 18 so that the wire is bent around the former roller 112 and to one side of the line of travel of support block 115, thus giving the proper contour to the hook. Suitable mechanism is preferably provided for holding the wire against movement during formation of the hook. As illustrated, forming the cam face 78' ing lever 78, see Fi 6, will be mo'mentari Body forming mechanism.

The body formingmechanism includes a pair of pivoted arms 132 (Figs. 1 and 20) which are sup orted to swing ust above the bed plate anti around vertically extending posts 133 secured to the bed adjacent the op posite ends of former plate 90. Surrounding each post 133 is end of this sprin is secured to a tensionmg block 135 which is held in adjusted position by means of a locking pin 136. The lower end of each spring is bent as shown at 137 and the bent end hes on a hole formed in the top of the adjacent forming arm. The upper end of each s ring is bent asjshown at 138 and d lies within aghole formed in the this is accomplished bya coil spring 134. The upper.

After-the wire has been severed and thev hook is formed, the formin' arms are moved position,

Fig. 20

and the length of wire is bent into the general form of a hanger.v

shown by dotted lines,

Each of the forming operative face is provi shown in Fig. 20, the former plate 90 will lie within the c anne-ls. As the arms are swung to forming position (full lines Fig. from inoperative position dotted lines Fig. 20), the wire is caught by t e channels in the ends of the forming arms at points 140 and car- Iried into contact with the edges of the former 1 arms 132 into forming position through the 5 plate and pressed into shape to form the body of the hanger.

A cam 141 (Fig. 19) keyed to the main shaft 32 of the machine forces the forming agency of a cam lever 142, an adjustable link 143, a lever 144 and chains 145.

Lever 142 is pivotally mounted in a bracket 146 secured to the under side of the bed. This lever carries a roller 147 with which the cam 141 contacts. Lever 144 is pivotally mounted at 148 to theouter end of a bracket 149 the upper end of which is secured to the frame of the machine. The upper endof lever 144 by means of a pair of links 150 is connected to a block 151 which is mounted to slideon a horizontal rod 152, rigidly secured to the bed 153.

Each of the chains 151 at one end and to the outer or free end of one of the forming arms 132 at the other end, as shown at 154, Figs. 1 and 20. P

A cushioning spring 155 is interposed between the'inner end of sliding block 151 and the mounting member 156 for the horizontal rod 152. Idler s rockets 157 one for each chain, are mounte for rotation above the bed and in the plane of movement of the chain.

' These sprocketsmeshwith the chainsand cause the chainsfto swing the formin arms inwardly fromthe': sition shown in Fig. 1 and by dotted lines 20 to. forming position asshown b full lines, Fig 20.

A curved track or way is provided for each side of the machine and each of these tracks is bolted to the bed. The track for the hooked end of the wire is-numbered 158,

bered 159. The inner concave face of each track member is provided with a wire guiding slot; or channel 166 within which its and of the wire moves while being bent around the former plate.-

k Twistingmeohanimn.

The twisting mechanism includesa twister head 161 which when in twisting sition is located on the median line, of 't e former plate 90. The twister headais mounted on a shaft 162 which carries a crowngear 163.;

Trunnion-like memberj166 is journaled within a bearing 171 which is also carried by support bracket 170. On this trunnion-like member 166 a gear 172 is keyed and secured to shaft 167 is a gear173.

' Gear 172 meshes with a rack 174 which is mounted'for vertical reciprocation within a guide way 175. A rack 176 meshes with gear 173 and this rack is mounted for vertical reciprocationwithin guide way 177 The outer end of trunnion-like member 166 is reduced in diameter as shown at 178 and pinned to the outer end thereof is an abutment member 179. This reduced portion also carries a sleeve-like member 180. A coil spring 181 having one end thereof secured to a utment member 179and the other end secured to sleeve 180 surrounds the reduced, portion of trunnion 166.

Spring 181 is stressed by rotating sleeve 180 and then by lockingjt to a stationary art of the machine such as the frame. This is done by means of a pin ,182 which projectsfrom the. sleeve 180 and which is caused to abut against an adjacent pbrtion of the frame lower limit of its travel.

An adjustable link 183 connects the lower end of rack 174 with thefree end of a swinging lever 184. The other end of this lever is pivoted the frame of the'machine. 4 This lever carries a cam contact roller 187 with which a cam 188 keyed to main shaft 32 contacts.

The head is slotted from side to side'as shown at 202 (Figs. 23, 24 and 25) and the sides of the slots are chamfered as shown at 203. Slot 202 is longer on. one side as shown at 204 than it is on the other as shown at 205. The intervening metal is curved as shown at 206 and provides a stop for the rear portion of the hook as the hook end of. the wire is forced into the twister head preparatory to twisting (Fig. 20). The hoo ed end of the wire enters the slot through the long while the straight end of the side wire enters the slot through the short side.

The head is provided with a hardened lower jaw 207 having a cylindrical shank 207' which is rigidly secured in position by means of a set screw 208. An upper jaw member 209 is Erovided with a c lin-drical shank 210 which ts within a bore ormed for that purpose inthe body portion of the head. A pin 211 threaded into the cylindrical shank-210 projects through an elon ated slot 212 formed in the body portion of the head.

vAn operating lever formed in the nature of a plate 213 is pivoted to the to of the body by meansof a shou dered screw 214. This lever has a slightly elongated hole 215 which'embraces the pin 211 and through which the pin extends. wThe construction is such that. as the lever is swung about its ivot,

' aw member 209 will be rocked on its s ank.

Hanger discharge and collecting mechanism.

This mechanism is shown in Figs. 1, 28, 29, and 30. A rod. 232 secured to sup rt bracket 170 extends forwardly of the mac e and adjacent its outer end carries an upright sup ort member 233. A plate 234 provided with an elongated slot 235 for securing vertical adjustment, is bolted to this upright support member. A lever arm 236 pivoted to plate 234 at 237 is yieldingly held in normal position against a sto 238 .by means of a spring239. That portion of the lever which projects beyondthe plate serves as a knockout agent and assists the hangers in leaving the gate and the space between jaws 207, and 209. This action is graphicallyillustrated in Fig. 26. The gate opens as jaw 209 is rocked on its shank since one beveled end of the gate contactswith 'aw 207.

Located in t e path of the hangers leaving the twister head is a member 240. This member is pivoted to the plate at 241 and is held in normal position b means of a s ring 242. The upper surface 0% member 240 is inclined as shown in Figs. 28 and 30 and as the hangin Fig. 26, the inner the outer end of this i of member 2 407and the i cm fall to the position shown by dotted, lines I of cam 193. made, cam 188 causes the twister head to twisting movement and during the swinging dicular.

hangers slide down this member and onto a collecting bar 243 down which they slide to the point-of removal.

Rod 232 carries a horizontally disposed rod 244 which serves as a stop to prevent the hangers from unhooking from member 240 as they tilt from full line position to dotted line position shown in Fi 26.

Operation.

In starting up the machine the end of the wire from the coil is 'fed through the pinch rolls through the straightening rolls and into cutter block 23. When the wire propelled by the pinch rolls, reaches the opposite end of the machine from said rolls, it contacts with the abutment or stop member 84 and lever 61 is thereby moved out of contact with the end of lever 64 and the feed of the wire by the pinch rolls erates lever 61 is so timed that the feed of the wire should stop at this time but the precaution is taken of positively stopping the pinch rolls as soon as the wire reaches its position in the machine.

Immediatel after the wire reaches its position cam 12 l reciprocates the hook forming roller 112 and the wire is bent around the roller and between stop pin 110 and grooved roller 111.. During formation of the hook, cam 82 reciprocates cutter 7 5. and severs the length of wire. 1

As soon as the wire the hook formed, cam 105 raises the guiding bar 96 to release the wire and cam 141 causes the former arms to swing and force the wire around former plate 90 and into the twister head where it is automatically locked inposition by sliding gate 217.

Cam 141 is so shaped that the former arms 132 will hold the wire in contact with formerplate 90 during-the twisting operation which is immediately caused to take place by means As soon as thetwist has been swing about the axisof crown gear 168 from twisting position to discharge position. The cam 193 is formed so that as soon as the twist has been made the twister head will begin to rotate in the opposite direction from the of the twister head from twisting to discharg ing position. Just prior to the time the twistor head reaches discharging position, pawl 226 by contacting with the bed of the machine will lock the twister head against iurtherrotation in the direction in which it has been rotating. This is adjusted so that the plane of the hanger to be discharged will be perpen- As the twister head approaches discharge ing position. lever 213 upon contacting with the other end of actuator screw 230 will rock jaw 209 and gate 217 will thereby be forced into open position by its lower beveled edge contact with knock-out then fall to the position illustrated by dotted length of wire into position in 'and a new cycle of operation will be started.

is stopped. Cam 62 which ophas been severed and 218 and thefinished hanger will pass below detent 240 which serves as a gate,

is to be removed for packing.

As soon as the twisting operation has been completed the former arms will be forced back to initial position by means of springs 133. Y lVhen they reach this position, guide bar 96 will be allowed to drop to guiding po sition and the pinch rolls will force another the machine Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is 1.
